基于unity的2d动画制造----基于c#说话开辟，类似于《DNF》的2d界面，今朝只有一个游戏场景。结不雅图UI如下图所示

游戏结不雅视频已经上传B站：

2dAnimation游戏

游戏开辟重要步调：

1.素材收集（来自Unity的Asset Store）

2.UI设计（随心所欲）

3.刚体碰撞规矩等（csharp代码）

Hierarchy的┞符体构造如下：每个物体的名称和它的英文名大年夜概一致。

脚本构造如下：

部分PlayerController的代码如下：

在这里插入代码片

EnemyController的部分代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//author:刘家诚：date:2020.10.16
//仇敌控制相干
public class EnemyController : MonoBehaviour
{
    private float speed = 7;

    private Rigidbody2D rbody;
    //是否垂直
    public bool isVertical;

    public float changeDirectionTime = 2;

    private float changeTimer;//急鹞鲼

    private Vector2 moveDirection;//移动偏向

    private Animator anim;

    private bool isFixed;//是否被修复


    // Start is called before the first frame update
    void Start()
    {
        rbody = GetComponent<Rigidbody2D>();//获取刚体

        moveDirection = isVertical ? Vector2.up : Vector2.right;//断定是否垂直

        changeTimer = changeDirectionTime;

        anim = GetComponent<Animator>();//获取anim

        isFixed = false;
    }

    // Update is called>void Update()
    {
        //被修复，不履行以下所有代码
        if (isFixed) return;
        changeTimer -= Time.deltaTime;
        if (changeTimer < 0)
        {
            moveDirection *= -1;
            changeTimer = changeDirectionTime;
        }

        Vector2 position = rbody.position;
        position.x += moveDirection.x * speed * Time.deltaTime;
        position.y += moveDirection.y * speed * Time.deltaTime;
        rbody.MovePosition(position);
        anim.SetFloat("movex", moveDirection. x);
        anim.SetFloat("movey", moveDirection.y);
    }
    private void OnCollisionEnter2D(Collision2D collision)
    {
        PlayerController pc = collision.gameObject.GetComponent<PlayerController>();
        if (pc != null)
        {
            pc.ChangeHealth(-1);
        }
    }
    public void Fixed()
    {
        isFixed = true;
        rbody.simulated = false;
        anim.SetTrigger("fix");//播放被修复的动画
    }
}

BulletController的代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//author:刘家诚：date:2020.10.16
/// <summary>
/// 控制枪弹的移动
/// </summary>
public class BulletController : MonoBehaviour
{
    Rigidbody2D rbody;
    // Start is called before the first frame update
    void Awake()
    {
        rbody = GetComponent<Rigidbody2D>();
        Destroy(this.gameObject, 2f);
    }

    // Update is called>void Update()
    {
        
    }
    public void Move(Vector2 moveDirection,float moveForce)
    {
        rbody.AddForce(moveDirection * moveForce);
    }
    //=====碰撞检测=====
    private void OnCollisionEnter2D(Collision2D collision)
    {
        EnemyController ec = collision.gameObject.GetComponent<EnemyController>();
        if (ec != null)
        {
            Debug.Log("碰着仇敌了");
            ec.Fixed();//修复仇敌

        }
        Destroy(this.gameObject);
    }

    
}

Dangerous的代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//author:刘家诚：date:2020.10.16
public class Dangerous : MonoBehaviour
{
    //伤害陷阱
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called>void Update()
    {
        
    }
    public void OnTriggerStay2D(Collider2D collision)
    {
        PlayerController pc = collision.GetComponent<PlayerController>();
        if (pc != null)
        {
            pc.ChangeHealth(-1);
        }
    }
}

Collectable的代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//author:刘家诚：date:2020.10.16
public class CollectAble : MonoBehaviour
{
    //草莓被玩家碰撞时检测的相干类
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called>void Update()
    {
        
    }
    private void OnTriggerEnter2D(Collider2D collision)
    {
        //检测到有PlayerController
        PlayerController pc = collision.GetComponent<PlayerController>();
        if (pc != null)
        {
            if (pc.MyCurrentHealth < pc.MyMaxHealth) {
                pc.ChangeHealth(1);
                Destroy(this.gameObject);
            }
            

        }
    }
}
